I am a Christian–a Baptist, living in the Bible Belt. Granted, I am a Christian Democrat, but there we are. I think myself a moderate, as the position of where my views are on the conservative-liberal continuum depend on the issue.

Obama is a Christian. To say otherwise is to forget the time where he had to distance himself from his long-time Christian pastor (and, according to media coverage, mentor) in 2008 when said pastor was being inflammatory against Hillary (in a rather racist fashion). Obama waited a long time to disavow his association, but ultimately did so when the guy wouldn’t stop despite being asked to.

And Obama has given a rather fantastic speech specifically and at length about his faith at the Sojourners’ Call to Renewal conference in 2006.

In 2006. Before he ever decided to run for president.

This speech about his faith was one of the reasons I liked him so much when he ran back then.

JEDIT: He talks about when he gave his life to Christ at 14:50 in that video. I’m watching this video as I write this and it really speaks to me, as a man of faith myself, as coming from a man whose faith is genuine and heartfelt.
